IBEATER-ROLL FOR PAPER-MILLS.

Specification of Letters Patent.

Patented Aug. 22, 1911.

Application filed August 12, 1910. Serial No. 576,823.

To all whom it may concern:

Be it known that we, Anomn R. l VILLIS and CHARLES D. MAnoNny, citizensof the United States, residing at Elkhart, in the county of Elkhart andState of Indiana, have invented certain new and useful Improvements inBeater-Rolls for Paper-Mills, of which the following is a specification.

This invention relates to beater rolls for paper mills, and one of theprincipal objects of the same is to provide a comparatively light anddurable roll for the purpose referred to, in which the bars can bereadily renewed or removed from the roll whenever required without theuse of special tools.

Another object of the invention is to provide a beater roll comprising aseries of interior spider wheels, and a pair of end dis {S securedtogether upon a central shaft and having the bars secured to saidspiders and disks, by means of projecting pins and wedge blocks.

These and other objects may be attained by means of the constructionillustrated in the accompanying drawing, in which,

Figure 1 is a side elevation of a beater roll made in accordance withour invention. Fig. 2 is a sectional view on the line 2-2 of Fig. 1looking in the direction indicated by the arrow. Fig. 3 is an end Viewof the roll.

Referring to the drawing the numeral 1 designates the hub of a spiderwheel and 2 are the spokes connected to said hub and provided with a rim3. Extending outward from the rim is a series of lugs 1, each providedwith a socket 5. As shown in Fig. 1 there are three of the spider wheelsbut it will be understood that any suitable number may be used. At theend of the roll the heads are unbroken forming disks (5, each providedwith a hub 7, through which the shaft projects. The end heads 6 are alsoprovided with lugs 8 spaced apart around the periphcries thereof, saidlugs being provided with sockets 9, as shown more clearly in Fig. 3.

The heater bars 10 extend from end to end of the roll and are bent inthe center, as shown in Fig. 1. These bars are each provided with pins11 which are adapted to fit in the sockets 9 and 5 in the lugs S and 1.For holding the bars in place and for preventing the pins 11 from beingwithdrawn from the sockets 5 and 9, wedge blocks 12 are inserted betweenthe lugs and the next adjacent bar, as shown more clearly in Figs. 2 and8. The wedge blocks 12 serve to hold the pins into the sockets in thelugs, thus securely holding the bars in place to permit them to bereadily disconnected from the roll for repairs or renewals.

From the foregoing it will be obvious that a beater roll made inaccordance with our invention; is con'lparativcly simple in coirstruction; can be manufactured at low cost; is strong durable andcllicient for its pur pose; can be quickly assembled; and can be readilyrepaired whenever injured.

We claim:

The herein described beater roll for paper mills comprising a series ofspiders having peripheral lugs cast thereon, said lugs each beingprovided with a socket, heads for said beater roll also provided withsocketed lugs on the peripheries thereof, beater bars connected to saidlugs by means of pins extending into the sockets of said lugs, said pinsbeing formed integrally with the bars, and wedge blocks for holding thepins in the sockets of said lugs, said bars being bent cent-rally asshown and described.

In testimony whereojl we alliX our signatures in presence of twowitnesses.
